Antibody treatment benefits leukemia patients receiving bone marrow transplant

An experimental antibody that delivers lethal radiation directly to the bone marrow improved the outcomes of stem cell transplants for older patients with relapsed leukemia — and may change the way transplant medicine is practiced.

The antibody-radiation treatment, called Iomab-B, is being developed by Actinium Pharmaceuticals, a small drugmaker based in New York.

In the results of a Phase 3 clinical trial presented Saturday, 22% of patients with acute myeloid leukemia who were administered Iomab-B to prepare their bone marrow for transplants had durable remissions lasting six months or more. None of the patients in the study who received conventional care prior to transplant achieved durable remissions.
